چکیده انگلیسی
In this work, we prepared Al-7075/B4C composites by milling powder mixtures using a shaker-mixer mill, sintering the milled mixtures using plasma activated sintering (PAS), and heat treating the sintered product. To characterize the microstructure of the composites, we used field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). Al-7075/B4C composites can be prepared by PAS with high relative densities at low temperature. Increasing the B4C content increased the hardness, bending strength, and compressive yield strength of the composite. However, adding too much B4C caused B4C agglomerates to form, decreasing the hardness and bending strength of the composite. At 7.5 wt.% B4C, the Vickers hardness, bending strength, and compressive strength of the consolidated samples were 184.3Â HV, 813Â MPa, and 895Â MPa, respectively. We attributed these superior mechanical properties to good interfacial bonding between the matrix alloy and the reinforcement.
